Roman Kagan 9445597b6a i386/hyperv: add hv-frequencies cpu property 
In order to guarantee compatibility on migration, QEMU should have
complete control over the features it announces to the guest via CPUID.

However, the availability of Hyper-V frequency MSRs
(HV_X64_MSR_TSC_FREQUENCY and HV_X64_MSR_APIC_FREQUENCY) depends solely
on the support for them in the underlying KVM.

Introduce "hv-frequencies" cpu property (off by default) which gives
QEMU full control over whether these MSRs are announced.

While at this, drop the redundant check of the cpu tsc frequency, and
decouple this feature from hv-time.
